Cellulose-based materials are one of the most significant candidates for the preparation of a number of copolymers by graft copolymerization owing to their linear structure, providing good reinforcing properties to the resulting copolymers. Therefore, in the present study, in an effort to develop novel low-cost ecofriendly green polymeric materials, graft copolymers based on lignocellulose were synthesized by graft copolymerization of methyl methacrylate. Different reaction parameters were optimized to get the optimum graft yield, and the graft copolymers were subjected to the analysis of different physicochemical properties.
